Title: Automatically acting brake for trailer cars
IPC: B60T7/20
Filed: 1928-03-27
Abstract: 287,875. Iversen, P. A. S. March 28, 1927, [Convention date]. Actuated or applied by backward pressure of tractor or relaxation of pull or push; band. - Brake mechanism for a trailer vehicle whereby the brakes on that vehicle are automatically applied both in forward and rearward running the relative movement of the two vehicles which takes place when the speed of the tractor is reduced comprises according to one construction a brake band 2 which is free to turn about the axis of the brake drum of the trailer 1 to a limited extent determined by the engagement of abutments 9 on the band with fixed stops 10. A cranked lever 4, 5 is connected directly to one end of the band and by a link 6 to the other end of the load. The lever is connected also to a rod 13 arranged to slide under the constraint of a spring 27 in a casing 16 forming part of the rod 17 by which the trailer is coupled to the tractor. Sliding movement of the rod 17 in both directions is constrained by a spring 18. With the vehicles at rest, the parts occupy the position shown in Fig. 1 and the brake band is released. When the tractor pulls on the trailer, the lever 4, 5 is turned by the outward movement of the rods 17, 13 and the brake band is momentarily tightened about the drum which however immediately carries the band around to a limited extent so that the band is again released as shown in Fig. 6. If in these conditions the speed of the tractor is reduced so that the trailer advances on the tractor, the relative inward movement of the rods 17, 13 again tightens the brake band which is carried around by the drum until the forward pair of stops 9, 10 are in engagement. Following an application of the brakes in this way, release is effected if the tractor again exerts a pull on the rods 17 or if the tractor moves backwards after a complete stop, the reversal of the rotation of the brake drum in this case causing the release of the band although the rods 17, 13 are in the inner position. The brakes are applied in backward running if the tractor speed is reduced. The lever 4, 5 may be replaced by a double bell-crank connected by links to the ends of the band or an internal shoe brake expanded by a floating cam may be used.

Abstract: 472,900. Television. RADIOAKT.-GES. D. S. LOEWE. March 28, 1936, Nos. 9262 and 9263. Convention dates, March 28, 1935 and Nov. 4, 1935. [Classes 40 (iii) and 40 (v)] A modulator 16 for synchronizing signals, which can reduce the high-frequency current to zero, co-operates with a modulator 9 for image signals which cannot reduce the highfrequency below a definite residual value. An apparatus 5 controls the peaks of the image signals so that black in the image reduces the electronic current in the valve 9 to zero. The valve is bridged by an adjustable impedance 11 to ensure that a minimum highfrequency current can always pass in the same phase as the electronic current. The capacitative coupling between the grid and anode circuits may be by the internal capacities of the valve. A screening-grid in the synchronizing modulator is earthed at high-frequency by condensers or a series resonant circuit 17, 18. According to modifications, the modulation may occur in a single pentode or hexode, Figs. 3 and 4 (not shown). The anode circuit may be tuned to a harmonic of the high-frequency supplied to the controlling grid. Specifications 457,879 and 465,915 are referred to.

Filed: 1965-03-08
Abstract: 1,092,785. Grinding. FABRIK FUR FIRESTONE PRODUKTE A.G. March 8, 1965 [March 26, 1964], No. 9785/65. Heading B3D. [Also in Division B4] Apparatus for cutting an elongate web of material, which may be, e.g. rubber, cord fabric, aluminium, synthetic resins or paper, into strips comprises means for continuously moving the web in a direction along the length of the web, and a cutting device or devices 6 mounted on a carriage 18, Fig. 8, which is slidably mounted on a first guide rail transverse to the web. Drive means moves the carriage along the first guide rail simultaneously with movement of the web to cut or part the web into strips defining an acute angle with the length of the web. A second guide rail returns the or each cutting or parting device to the one side of the web at which the cutting or parting is started. Transfer devices transfer the or each cutting or parting device from one guide rail to the other. As described, the web is unwound from a drum, and passes over roller on to an endless belt 10, Fig. 1, past cutters 6, supported by a structure 20. The structure 20 comprises four arms 19 each pair supporting guide rails 13, at each end of which are rotary discs 24. These include spaced rail members 32 which form continuations of the guide rails. The carriage 18 bears an electric motor 12 for a cutting wheel 7 running on the lower guide rail 13, when in operation. The belt 10 is driven by an electric motor 46 through a gear-box 48 and pulleys and belt 56, 51, 52 and the same motor also drives a worm shaft 14, Fig. 8, which traverses the cutting device 6 along the lower rail 13, the device being moved back along the upper rail. Transfer of the cutting devices between rails is effected by rotatable discs 24. Movement of the right-hand disc is effected by a switch actuating a ram, rack and freewheel pinion arrangement 38, 39, 40, and locking by a ram 42 and stop 41 a similar arrangement operating the other disc. As the cutting device 6 moves off the lower rail 13 on to the aligned guide member 32 the device contacts a switch so that the disc 24 is rotated until the device is aligned with the upper rail 13. A chain 22, Fig. 8 engages a catch 23 on the carriage 18 and the device is moved along the upper rail in the direction of the arrow E. The cutting device is thus moved on to the guide member 32 of the left-hand disc 24, which is rotated to bring the device 6 into alignment with the lower guide rail. The carriage 18 is only moved by the worm-wheel 15 when the carriage is on the lower guide rail, and at other times the wheel runs freely in the carriage by operation of an electromagnetic clutch 16, which is operated by a contact actuated by one cutting device 6. The position of the contact is adjusted to vary the width of strips cut. False cuts in the belt are prevented by a contact breaker which opens when there is no cutting device at the starting position at the edge of the belt to interrupt movement of the conveyer and rotation of the worm shaft 14.
